STOVEPIPE-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 646,881, dated April 3, 1900.

Application filed April 28, 1899. Serial No. 714,859. (No model.)

To all whom t may oon/cern:

Be it known that I, DAVID W. SMITH, a citizen of the United States, residing at Smithton, in the county of Pettis and State of Missouri, have invented certain new and useful Improvements in Stovepipe-Fasteners; and I do hereby declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to .which it appertains to make and use the same.

. means of attachment of the wires and replace such Inode of secureinent by devices directly applied to the pipe adjacent the chimney-flue, in part entering the flue-opening and so arranged that the inserted end of the pipe will be prevented from moving after the several parts are secured, and thereby insure a uniform draft and also obviate entrance of dust from the flue into a room or compartment.

The invention, generally stated, consists of a collar intimately related to a clampingband and locking-straps held closely to the stovepipe by said band and having a rear connection extending across the end of the pipe within the ue to serve as a rear limit or stop and act conjunctively with the collar and band to removably secure the pipe in a predetermined manner in the flue-opening.

The invention further consists of the details of construction and arrangement of parts hereinafter more fully described and claimed.

In the accompanying drawings, Figure l is a perspective view of a stovepipe-fastening embodying the invention and shown applied. Fig. 2 is a longitudinal vertical section of the device as shown by Fig. 1. Fig. 3 is a detail perspective view of the locking-straps and the rear fastening therefor.

Like characters of reference are employed to indicate corresponding parts of the several views.

Referring to the drawings, the numeral 1 designates a flue opening constructed, as clearly shown in Fig. 2, and adapted to receive a stovepipe 2 or analogous conduit. As shown by Figs. l and 2, a 'collar 3 of well-known form is employed and surrounds the flue-opening 1 and the pipe 2. Adjacent the contracted portion of the said collar 3 a clamping-band 4 is located, provided with angularly-bent ends, which receive a clamping bolt or pin 6. The inner endof the band 4 is dared to form an annular shoulder 4% which overlaps the collar 3. Between theclamping-band 4, the collar 3, and the pipe 2 locking-straps 7 are positioned and bear closely against said pipe 2, being united at the rear ends withinthe chimney-lue and close to the inner termination of the lue-opening l by a pin 8, which projects sufficiently beyond each of said straps as to form a stop to prevent withdrawal of this part of the device.

In assembling the parts described the straps 7are first pushed into the flue-opening 1 and suitably connected bythe rod 8. The pipe or other conduit 2 is then shoved into place, as shown by Fig. 2, the collar 3 slipped over the pipe, and straps and the clamping-band 4 then tightly drawn around all the parts and secured against expansion by means of the bolts 6. After these partsare so arranged the projecting ends of the straps 7 are upset over the adjacent edge and at opposite points of the clamping-band 4. It will be observed that the clamping-band 4 braces against the edge of the reduced portion of the collar 3, which serves as a stop, and by the use of the rod 8 and through the medium of upsetting the ends of the straps over the adjacent portion of the clamping-band the pipe or conduit 2 is immovably held and a tight joint is inserted, as the said straps are not thick enough to leave a material opening or crevice between the pipe or conduit and the Wall of the flueopening, being preferably formed of sheet metal suiciently strong to serve the purpose of a fastening.

This form of fastening may be applied to any kind of pipe or conduit and used for other purposes where it is found convenient, and to accommodate various forms of applications changes in the minor details of construction, as well as the proportion and dimensions,may be resorted to without in the least departing IOO from the nature or spirit of the invention or l serted, and having their outer ends bent to sacrificing any of the advantages thereof.

Having thus described the invention,\vliat is claimed as new is- The combination with a stovepipe, and a collar surrounding the same, of a clampingband flared at its inner end to form a shoulder which overlaps the coller; a bolt for securing the ends of the clamping-band; straps arranged on the outer side of the pipe at diat metrically opposite points and extending through the opening in which the pipe is inengage the clamping-band; and a rod securing the inner ends of the straps, said rod projecting beyond the straps to form stops, and serving to hold the overlapping shoulder of the band in close connection with the collar. In testi1nonT whereof I affix my signature in presence of two witnesses.
